1.水稻稻瘟病长期灌深水或过分干旱、偏施氮肥等导致稻瘟病发病重。水稻一生中有3个易感病时期,分别是苗期、分蘖盛期和抽穗齐穗期。穗颈瘟对水稻产量影响最大,应在破口期及齐穗期及早预防。稻瘟病分苗瘟、叶瘟、节瘟、穗颈瘟和谷粒瘟。防治应采用以种植抗病优质品种为中心、健身栽培为基础、药剂保护为辅的综合;防治措施。1合理利用抗病品种。2科学田间管理。培育壮秧,施足基肥,增施钾肥、锌肥、有机肥,巧施穗肥,适时晒田。3种子处理。10%401抗菌剂1
1. Rice blast long-term irrigation deep water or over-drought, partial nitrogen fertilizer lead to the incidence of rice blast disease. Rice has three susceptible stages of life, namely, seedling stage, tillering stage and heading stage heading stage. Panicle blast has the greatest impact on rice yield and should be prevented early at breach and heading stage. Blast blight seedling blast, leaf blast, section blast, panicle blast and grain blast. Prevention and treatment should be used to plant disease-resistant varieties as the center, based on fitness cultivation, supplemented by a comprehensive pharmaceutical protection; prevention and control measures. A rational use of disease-resistant varieties. 2 scientific field management. Nurturing strong seedlings, Shizujifei, an increase of potash, zinc, organic fertilizer, Qiao Shi Suan, timely sunning. 3 seed treatment. 10% 401 Antimicrobial 1
